K-Secret Retinal Liposome 2% + Black Ginseng Serum at a glance

Retinal is a genuine, potent retinoid — read this before you start

Retinaldehyde (retinal) sits between retinol and prescription tretinoin on the retinoid conversion pathway, and it tends to work faster and, gram for gram, more intensely than retinol. The "liposome complex" in the name means the retinal is encapsulated in lipid carriers, which buffers irritation and controls release — but it doesn't change the two things that matter most: retinoids increase sun sensitivity, so daily sunscreen is required, and they're contraindicated during pregnancy and breastfeeding.

On the labeled "2%": that figure describes the retinal-liposome complex, not necessarily 2% of free retinaldehyde — most over-the-counter retinaldehyde products use 0.05–0.1% free active because it's so potent. Either way, this is a genuine retinoid and deserves real caution: patch test first, and if you're new to retinoids, don't start here — build tolerance with a lower-strength product first.

Black ginseng contributes antioxidant support and is generally well tolerated, but it's a supporting ingredient, not the reason this serum works.

How to use it

1. Patch test on your inner arm for 48 hours before first facial use.
2. Apply at night to cleansed, dry skin — two to three drops.
3. Start two to three nights a week, even if you already use retinol elsewhere.
4. Follow with moisturizer to buffer dryness while your skin adjusts.
5. Wear sunscreen every morning — non-negotiable with any retinoid.

Frequently asked questions

Can I use this during pregnancy or breastfeeding?

No. Retinal is a true retinoid and retinoids are contraindicated during pregnancy and breastfeeding. Speak with your doctor about non-retinoid alternatives such as bakuchiol or peptide serums.

Is this stronger than a regular retinol serum?

Generally yes. Retinaldehyde converts to retinoic acid in fewer steps than retinol, so it tends to act faster and more intensely at an equivalent percentage. The liposome encapsulation here helps buffer that, but it's still a potent retinoid.

What does the "2%" on the label actually mean?

It refers to the retinal-liposome complex concentration, not necessarily 2% of pure free retinaldehyde. Most over-the-counter retinaldehyde products use 0.05–0.1% free active because of how potent it is. Treat it as a genuine retinoid either way and introduce it gradually.

Will it irritate my skin?

It can, especially in the first few weeks — dryness, flaking, and mild redness are common with any retinoid. Starting at two to three nights a week and moisturizing well reduces this.

Can I use it every night?

Not right away. Build up gradually over several weeks based on how your skin tolerates it. Daily use isn't necessary for retinoids to work.

Do I need sunscreen with this?

Yes, every morning without exception. Retinoids increase photosensitivity, and retinal itself degrades in sunlight, which is why it's formulated as a night-only serum.
